So many broken breaker bars ..so so many fallen to the cause at the front line , the big and the small succumb eventually , none have stood the test of time all eventually reach the end . We mourn their loss, but move on as they would have wanted.
I've been abusing a Halfords 1/2" version for the last 15 yrs - and it was abused in a work communal toolbox for a few years before that. Got some slop in the joint, but just keeps on going.
